Abstract: Abstract: Multi-source and heterogeneous Earth Observation （EO） data is widely used in different fields of national economic construction. However， different spatial reference frames have been increasingly adopted for data of different types， sources and sectors， which pose a big challenge to the sharing of spatial information of different reference frames. Promisingly， the combination of global subdivision grid and Web services provides a fine solution to such a problem. Among them， the Beidou grid has the characteristics of simple segmentation structure and easy to use， which can assist in retrieving image data. Web services can be used for image data retrieval under the Beidou grid code identification. Therefore， this paper takes the Beidou grid as a reference， establishes the mapping relationship between grid and image data， proposes a Beidou grid description method and image data acquisition method for remote sensing image data， and designs a prototype of Beidou grid image description Web service and Beidou grid code based image data acquisition Web service based on RESTful architecture， achieving interoperability of image data using grid as a unit under the same reference framework.
